You remember those names, don’t you? At one point, Fiesta was associated with HTC’s Tattoo (pre-release), though that appears to have been a case of mistaken identity. The first image below, which CellPassion is calling Fiesta, doesn’t have the right button configuration to be attached to Tattoo. Then again, the photo could represent a scrapped prototype – as CP supposes – and possibly the predecessor to Tattoo. The second picture features the HTC Paradise, which is basically an Aria with a slide-out QWERTY. This one could still be headed for AT&T.
The story is that a CellPassion reader found some AT&T Androids for sale on CraigsList and enlisted the site for gadget identification.
